Well, after seeing the retarded way the apron is done it doesn't surprise me that the cracks showed up where they did.
First, the apron should indeed have been done different IMO. The curbs should have been cut back from the driveway and sloped/radiused in. The only possible problem is that there may be issues with the city on cutting the curbs.
The cracks both appear to be at the stoop by the side door??
This gets tricky because that stoop may move with the house or it may not, either way it's gonna move if you have freezing weather, and it may or may not cause cracking of the drive. The drive should have been more carefully isolated from the stoop somehow.
Compaction under the new drive area may have been an issue also.
That said, if there's one thing you can be sure of with concrete, it's that it WILL crack.
Where it cracks and how much is the only variable.
The apron?? There's 2 ways to get something done your way. #1 is to do it yourself, #2 is to make damn sure the person that is doing it knows what you want. If you have to, hold their hand while they do the job.
